Use shorter error messages for whitespace problems

The initial version of the whitespace_error_string() function took the
messages from builtin-apply.c rather than the shorter messages from
diff.c.

This commit addresses Junio's concern that these messages might be too
long (now that we can emit multiple warnings per line).
